Holland’s submarines paved the way for modern underwater vessels, playing a crucial role in naval warfare and scientific exploration. His designs influenced submarines used in both World Wars and continue to inspire advancements in deep-sea technology.

The Hypodermic Syringe

In 1844, Dublin-based surgeon Francis Rynd introduced a hollow needle for the syringe, transforming drug administration. This Irish invention replaced cumbersome earlier methods and enabled precise injection of medication, paving the way for modern vaccination and other crucial medical procedures.

Rynd’s invention revolutionised modern medicine, enabling safe and effective delivery of life-saving vaccines and medication. It has played a central role in controlling infectious diseases, improving public health, and enhancing the effectiveness of various medical treatments.

The Binaural Stethoscope

Irish physician Arthur Leared refined the stethoscope in 1851 by adding two earpieces connected by rubber tubing. This “binaural” design allowed doctors to isolate and amplify sounds within the body with greater precision, significantly improving diagnosis and treatment.

Leared’s binaural stethoscope became the standard medical instrument for auscultation (listening to internal sounds). It is still widely used in various medical fields, enabling accurate diagnosis of heart, lung, and other internal conditions, ultimately improving patient care and outcomes.

The Three-Point Linkage System

1928, Harry Ferguson, a self-taught engineer from County Down, invented the three-point tractor linkage system. This revolutionary design allowed implements to be attached and manoeuvred with remarkable precision and ease, increasing agricultural efficiency and productivity.

Ferguson’s invention transformed agriculture on a global scale. It enabled farmers to cultivate land more effectively, reduce labour requirements, and increase crop yields. His system remains the industry standard and remains essential for modern farming practices.


Developed by Dublin pharmacist Thomas Smith in 1931, this skin protectant became a household staple. Its soothing properties helped treat nappy rash, eczema, and minor burns, making it a trusted family essential.

Sudocrem became more than just a cream; it symbolised care, comfort, and a time-honoured tradition passed down through generations. Its enduring popularity speaks volumes about the ingenuity of its creator, Professor Smith, and the timeless need for gentle, practical solutions to everyday skin concerns.

The Portable Defibrillator

Belfast physician Frank Pantridge revolutionised emergency medicine in 1965 with the portable defibrillator. This device allowed for rapid intervention in cases of cardiac arrest, dramatically increasing survival rates and making life-saving treatment readily available outside hospitals.

His prototype, nicknamed “Frankenstein,” was a far cry from sleek modern devices. Built from car batteries and repurposed parts, it weighed a hefty 70 kilograms and required two strong individuals to operate. Yet, it was a giant leap forward. In 1966, the first successful out-of-hospital defibrillation was performed with this clunky marvel, sending a jolt of hope through the medical community.

Pantridge’s invention did not stop there. He tirelessly refined his design, shrinking the device over time, making it lighter, easier to use, and ultimately, a tool available not just to doctors but also to paramedics and emergency personnel. This democratisation of life-saving technology was unprecedented.

The Breakfast Roll 

This seemingly simple Irish invention for breakfast in the 1990s, a soft roll filled with sausage, bacon, or egg – took Ireland by storm and quickly spread beyond its borders. The breakfast roll became a beloved on-the-go breakfast and lunch option, reflecting Irish culinary ingenuity and adaptability.

The “Tayto” Crisp Seasoning Technique

Joseph’ Spud’ Murphy and Seamus Burke from Tayto Crisps in Ireland revolutionised crisps by inventing the cheese & onion and salt & vinegar seasoning technique in 1950. This simple yet genius innovation became the standard for flavoured crisps worldwide, forever changing the snacking landscape. 

Flavoured Potato Crisps

Joseph “Spud” Murphy, the founder of Tayto crisps, developed the world’s first seasoned crisps – cheese & onion and salt & vinegar. These flavours quickly became a hit, revolutionising the snacking world and paving the way for the endless variety of flavoured crisps we enjoy today.

The Claddagh Ring

This intricate ring, made in the 1830s and originated in the Galway fishing village of Claddagh, symbolises love, loyalty, and friendship. The hands holding a heart topped with a crown represent love, the heart stands for loyalty, and the crown signifies friendship. The Claddagh ring became a famous romantic symbol and cultural icon, transcending Irish borders and capturing hearts worldwide.

The Transatlantic Telegraph Cable

While the transatlantic telegraph cable may not have been solely an Irish invention, the contributions of Irish engineers and entrepreneurs were instrumental in its success.

Joly Color Screen

Created by physicist John Joly in 1894, this ingenious system introduced the possibility of capturing vibrant colour photographs using a single plate. Joly’s method involved placing a screen with fine red, green, and blue lines in front of the photographic plate. Different light wavelengths interacted with the lines, creating a pattern that revealed the original scene in colour when viewed through a similar filter. While later technologies surpassed it, Joly’s invention paved the way for practical colour photography and inspired further advancements in the field. 

The Induction Coil

The induction coil, known as a “spark coil” due to its ability to generate high-voltage pulses, traces its origin back to Nicholas Callan, a Maynooth College in Ireland professor. In 1836, Callan built upon the work of Michael Faraday and others to create a more efficient and powerful device version. His design included two coils of wire wrapped around a common iron core, allowing for better magnetic coupling and higher voltage generation.
